举起活动的问题

问题描述

if（currentDesigner！= null）

{

e = new MouseButtonEventArgs（InputManager.Current.PrimaryMouseDevice，

e.Timestamp，

MouseButton.Left）;



currentDesigner.OnMouseLeftButtonDown（发件人为AnnContainer，e）;

}



在上面提到的代码中，我在最后一行得到一个例外（currentDesigner.OnMouseLeftButtonDown（发件人为AnnContainer，e）;）



例外：每个routedeventargs都必须有一个与之关联的非空路由事件。



请尽快回复



我尝试了什么：



我试图让e.Handled = false但是它不起作用

if (currentDesigner != null)
{
e = new MouseButtonEventArgs(InputManager.Current.PrimaryMouseDevice,
e.Timestamp,
MouseButton.Left);

currentDesigner.OnMouseLeftButtonDown(sender as AnnContainer, e);
}

In above mentioned code i am getting an exception in last line(currentDesigner.OnMouseLeftButtonDown(sender as AnnContainer, e);)

Exception:Every routedeventargs must have a non-null routed event associated with it.

Please reply as soon as possible

What I have tried:

I try to make e.Handled=false but its not working

推荐答案

e = new MouseButtonEventArgs(InputManager.Current.PrimaryMouseDevice, e.Timestamp, MouseButton.Left);
e.RoutedEvent = UIElement.MouseLeftButtonDownEvent;
currentDesigner.OnMouseLeftButtonDown(sender as AnnContainer, e);
